EarthThu, 21 Aug 2014 14:30:03 ESTnews327848680Scientists identify Deepwater Horizon Oil on shore even years later, after most has degradedYears after the 2010 Deepwater Horizon Oil spill, oil continues to wash ashore as oil-soaked "sand patties," persists in salt marshes abutting the Gulf of Mexico, and questions remain about how much oil has been deposited on the seafloor. Scientists from Woods Hole Oceanographic Institution and Bigelow Laboratory for Ocean Sciences have developed a unique way to fingerprint oil, even after most of it has degraded, and to assess how it changes over time. Researchers refined methods typically used to identify the source of oil spills and adapted them for application on a longer time frame to successfully identify Macondo Well oil, years after the spill.http://phys.org/news321802805.html

The iconic salt marshes of the famous summer retreat are melting away at the edges, dying back from the most popular recreational areas. The erosion is a consequence of an unexpected synergy between recreational over-fishing and Great Depression-era ditches constructed by Works Progress Administration (WPA) in an effort to control mosquitoes. The cascade of ecological cause and effect is described by Tyler Coverdale and colleagues at Brown University in a paper published online this month in ESA's journal Frontiers in Ecology and the Environment.http://phys.org/news278331029.html

Globally between a quarter and half of the area of the world's tidal marshes has already been lost, and although multiple factors – sea-level rise, development, loss of sediment supply – are known to contribute to marsh loss, in some locations the causes have remained unexplained.http://phys.org/news269695795.html

BiologyTue, 27 Sep 2011 11:57:10 ESTnews236343420It's no sweat for salt marsh sparrows to beat the heat if they have a larger billBirds use their bills largely to forage and eat, and these behaviors strongly influence the shape and size of a bird's bill. But the bill can play an important role in regulating the bird's body temperature by acting as a radiator for excess heat. A team of scientists have found that because of this, high summer temperatures have been a strong influence in determining bill size in some birds, particularly species of sparrows that favor salt marshes. The team's findings are published in the scientific journal Ecography, July 20.http://phys.org/news230398835.html
